I have been able to setup the Send Connector Logging and it works as expected, but I'm not getting any logging from the Receive Connectors. I have tried enabling via the EMC as well as via powershell and have even tried writing the logs to different locations with no success. They are seemingly not being written at all anywhere. Any help would be appreciated!
If you aren't seeing any protocol logging written then its possible you're not generating any SMTP traffic to the Receive Connector.
How are you testing this?
Keep in mind that email between two mailboxes on your Exchange server, even though it traverses the Hub Transport server, doesn't use the Receive Connector to do so and so it won't generate protocol logging.
